Obviously, but I assumed that at least some readers are only familiar with
hosted GCC implementations (or even embedded implmentations using chips that
have all of the instructions GCC normally wants to use) and didn't consider
what the effect of calculating a hash value via division if the machine in
question doesn't have a division instruction.
